Upgraded a paid of 6500 XGS to 19.5 GA last week without incident. However I've now noticed that any changes I make to the configuration of the firewall do not appear to affect it's operation. To troubleshoot\confirm this I've tried:
Disabling SSL/TLS inspection - still get entries in the logs for this and it appears to still be 'on'
Created an any/any rule for a specific host for outbound traffic with only logging enabled and placed it at the top of the rule list. Firewall logs show traffic still being handled by the usual egress rule but policy tester suggests the new rule should be in play.
Also noticed no effect when adding URLs to particular groups or categories, even though they appear correct in the configuration.
Anyone seen anything similar to this? It's very odd.
